No, the creator has been paid for the sponsorship beforehand. If you were never going to get the products that are sponsored then there's no difference between skipping it or letting it play and ignoring it.

I mean yeah, youtube does track the times in videos people do watch and are engaged in, but by skimming through almost any video you can see many people skip around and don't actually watch the full videos.

Sponsorblock just saves me from manually skipping past the sponsorships. I was never going to buy a shilled product to begin with anyway. I buy things based on my own research, not what a youtuber says I should buy.
